I bought a new laptop with following configuration:
640gb hard disk and 4gb RAM with pre installed windows 7.
right now the hard disk partition is dynamic in nature.
now I want to multi boot my system with windows 7 and ubuntu,may be A third OS in future. so kindly please suggest me the appropriate partition scheme along with the file system which can work efficiently.
roughly I want 3 primary and 1 extended partitions.I am not able to decide about the sizes of each.I need to share my data with both the operating systems.kindly mention in detail about the partition scheme ?
thanks in advance

The first thing you need to do is have windows convert the disk back to a basic disk, since only Windows can use dynamic disks. Then if you just install Ubuntu and tell it to install along side windows, it will automatically shrink the windows partition to make room to install Ubuntu. It will give you a slider so you can configure how much space to allocate to each.

Once Ubuntu is installed, it will be able to recognize the windows partition and you can store files there and be able to access them from Windows as well. If you plan on storing most of your files on the Windows partition, then 15-20 gb will be enough for Ubuntu.
